This guy does some seriously wicked mods for improving/customizing flash equipment. He rocks. He can custom make anything and does it right. His work is high quality with good attention to detail. He also will rebuild what you already have to be much more "bullet proof" with better metal shoe plates, tougher screws, etc.

My biggest concern with his work on flashes is that once the flash is improved, it will never fail and won't break so my camera will split in half instead! (Gotta hate it when that happens!)

I (again) didn't realize Canon does produce the same thing - and given Canon's current pricing policy, I think they should lower the prices so that they're only *10* times more expensive than the same thing from a third party, often they're even content with only 5 times like the ttl-cord or lens hoods :-p

Maybe you're better off with used pocket wizards or some cheaper version of them.

If I should get this than only to attach 1 or max two cheap flashes (like the ring flash advice above) near the camera, otherwise I'd invest in the current Canon wireless system (that's why I got the 600rt) though that isn't compatible with studio flashes atm.

The smiley was not for you, but rather the price. I just wanted to point out that all those adapters pretty much look the same.

Well, if you want to invest in the new wireless system of canon anyway, I don't think 10€ more will break the bank.Just give it a try? The cheapo manual ring flash is going to be the same kind of investment.

Yup, just ordered it directly from China (to save 5€ in comparison to a German delivery) - now I just have to wait a month :-> ... and I think the Canon flash system is currently overpriced since only the 600rt is available and I certainly cannot afford more of these, but I thought one would be a future-proof bet and it has the nice 200mm reflector.

if you want a perfect circle catch light in your subjects eye first determine the working distance you need and then look for the corresponding modifier.1. acrylic globe for home lighting (good for small dot or working close)... surprisingly cheap2. china lantern come in many diff sizes (good for small dot or working close).... surprisingly more cheap.3. use umbrella as close to lens as possible... some cases directly behind camera.4. any round box or octa bank or rotalux style bank.

only need a tenth of amount of light to produce specular in eyes... adjust to your liking but so it does not effect your main lighting ratio.
